Safety & Crime in Cairo

Dear community,

This is my first thread in Cairo community and I hoping that you guys may help us. My husband has received fantastic job opportunity to work in Cairo (actually New Cairo) for next 2 years.
Reading some articles online I got pretty scared on level of crime, sexual harassment (both verbal and physical), driving vs unsafe public transports and overall risk of terrorist attacks in Egypt and Cairo.
I would highly appreciate some experiences of expats who are already there and have experiences either positive or negative.
Maybe also do's and dont's.

Thank you all for commenting in advance 
